Water Meters

The City of Cornwall is installing water meters in every home and business. A meter measures exactly how much water you use.

Benefits for you:

• Fair billing: You will only pay for the water you actually use, not for the number of fixtures in your home.
• Control your bill: Understanding your water use helps you manage your costs.
• Find leaks: Your meter can help you detect hidden leaks early, preventing water waste and damage.

Meters help us find and fix leaks in the public water system quickly. This saves money for everyone and helps conserve our water supply.

Reading your meter

To monitor your daily water use:

• Take a reading at a set time of the day 
• Take another reading at the same time the next day
• The difference between the two readings is your 24-hour water consumption

Note: If the red sweep hand is moving when all your fixtures are turned off, you may have a leak.

Meter installations

Neptune Technology Group is installing water meters neighborhood by neighborhood, starting in the east end of Cornwall. When our installers are ready for your neighborhood, we will mail you a letter with instructions on how to schedule your appointment and prepare for the installation. Check our interactive map to find your area.

A legitimate installer will never ask you for money.

What to expect during your installation

During the appointment:

• The installation takes 30 to 90 minutes
• Your water will be temporarily shut off
• An adult (18+) must be home for the entire appointment

How to prepare:

• Clear a Path: Ensure the installer has clear, easy access to your main water shut-off valve

• Check your shut-off valve: Locate your main shut-off valve ahead of time and make sure it turns on and off easily
